Unformatted text preview: ch, equally spaced around the perimeter. If the
upper diameter at AA is 50 cm, and the lower diameter at BB is 25 cm, how many bolts
of the same size are needed around the perimeter at BB? H3.3 What is the mercury barometer reading at a location where the atmospheric
pressure is 99.0 kPa? 1 H3.4 Considering the effects of surface tension, estimate the gauge pressure at the center
of the pipe A. H3.5 If the sealevel pressure is 101,350 Pa, compute the standard pressure at an altitude
of 5,000 m, in two ways:
a) Using the exact relation (with the standard sealevel temperature and the lapse
rate of the standard atmosphere);
b) Using the isothermal assumption (temperature constant and equal to the
standard sealevel temperature) H3.6 If the pressure and temperature are 2.31 psia and 71.5° F at an elevation of 45,000
ft above sea level, what is the pressure at 55,000 ft assuming isothermal conditions over
this range of elevation? 2...
